Gas Products

Our refillable cylinders are made of steel or aluminum, and are designed for refilling

and repeated use. Some cylinders have been in service for over 40 years! Most refillable cylinders have an open interior with walls of 1/4 inch steel and a reinforced neck and bottom. Because commonly used gases

are highly pressurized (between 1,500 psig and 2,500 psig), cylinders must be maintained in good condition and protected from accidental damage at all times.
